If there are inputs without batch dim this should not be used and each input
should be overridden independently using-d option for input dimension
overrides.-s SYMBOL_NAME VALUE,--define_symbol SYMBOL_NAME VALUE
This option allows overriding specific input dimension symbols. For instance
you might see input shapes specified with variables such as :
data:[1,3,height,width]

quantization process. Format defined as per AIMET
specification.--input_list INPUT_LIST
Path to a file specifying the input data. This file
should be a plain text file, containing one or more
absolute file paths per line. Each path is expected to
point to a binary file containing one input in the
"raw" format, ready to be consumed by the quantizer
without any further preprocessing. Multiple files per
line separated by spaces indicate multiple inputs to
the network. See documentation for more details. Must
be specified for quantization. All subsequent
quantization options are ignored when this is not
provided.--param_quantizer PARAM_QUANTIZER
Optional parameter to indicate the weight/bias
quantizer to use. Must be followed by one of the
following options:"tf": Uses the real min/max of the
data and specified bitwidth(default)"enhanced": Uses
an algorithm useful for quantizing models with long
tails present in the weight distribution "adjusted":
Uses an adjusted min/max for computing the range,
particularly good for denoise models "symmetric":
Ensures min and max have the same absolute values
about zero. Data will be stored as int#_t data such
that the offset is always 0.--act_quantizer ACT_QUANTIZER
Optional parameter to indicate the activation
quantizer to use. Must be followed by one of the
following options:"tf": Uses the real min/max of the
data and specified bitwidth(default)"enhanced": Uses
an algorithm useful for quantizing models with long
tails present in the weight distribution "adjusted":
Uses an adjusted min/max for computing the range,
particularly good for denoise models "symmetric":
Ensures min and max have the same absolute values
about zero. Data will be stored as int#_t data such
that the offset is always 0.--algorithms ALGORITHMS [ALGORITHMS ...]

available optimization algorithms are:"cle"- Cross
layer equalization includes a number of methods for
equalizing weights and biases across layers in order
to rectify imbalances that cause quantization errors.--bias_bw BIAS_BW Use the --bias_bw option to select the bitwidth to use
when quantizing the biases, either 8(default)or32.--act_bw ACT_BW Use the --act_bw option to select the bitwidth to use

Use the --weight_bw option to select the bitwidth to
use when quantizing the weights, currently only 8bit(default) supported.--float_bias_bw FLOAT_BIAS_BW
Use the --float_bias_bw option to select the bitwidth to
use when biases are in float, either 32or16.--ignore_encodings Use only quantizer generated encodings, ignoring any
user or model provided encodings. Note: Cannot use
--ignore_encodings with --quantization_overrides
--use_per_channel_quantization [USE_PER_CHANNEL_QUANTIZATION [USE_PER_CHANNEL_QUANTIZATION ...]]
Use per-channel quantization for
convolution-based op weights. Note: This will replace
built-in model QAT encodings when used for a given
weight.Usage "--use_per_channel_quantization" to
enable or"--use_per_channel_quantization false"(default) to disable
--use_per_row_quantization [USE_PER_ROW_QUANTIZATION [USE_PER_ROW_QUANTIZATION ...]]
Use this option to enable rowwise quantization of Matmul and
FullyConnected op. Usage "--use_per_row_quantization" to enable
or"--use_per_row_quantization false"(default) to
disable. This option may not be supported by all backends.
使用 TF 转换器转换和量化模型的基本命令行用法如下：
$ qnn-tensorflow-converter -i <path>/frozen_graph.pb
-d <network_input_name><dims>--out_node <network_output_name>-o <optional_output_path>--allow_unconsumed_nodes # optional, but most likely will be need for larger models
-p <optional_package_name> # Defaults to "qti.aisw"--input_list input_list.txt
这将使用默认量化器和位宽（8 位用于激活、权重和偏差）来量化网络。
